The Brown & Sharpe TESA Tesatast series dial test indicator has a white face, a 0.0787" stem diameter, and inch measurements. The indicator can make either horizontal or vertical measurements, and the choice of white or yellow dial help make measurements easy to read. The yellow face with contrasting black hand complies with ANSI standards for metric dial faces. The carbide, ball-contact tip reaches into the workpiece for accurate measurements of turned, milled, and ground parts, and for tool setting gauges, fixtures, and inspections. The continuous clockwise pointer rotation helps prevent plus or minus confusion and displays reading in fractional inches. The ball-bearing lever system swivels through to 180 degrees. The dial face mounted at the top of the indicator parallel to the axis, and three universal dovetail mounts can be used for mounting from the top, front, or back. Dovetail mounts provide a rigid setup. This indicator has a Monoblock body design with pinions mounted in jeweled bearings in an isolated assembly separate from the outer body, for high accuracy. It is anti-magnetic for safety when used around magnetic workpieces and debris, and has full-metal construction for durability and corrosion resistance. This dial test indicator meets Deutsches Institut fur Normung (DIN) 2270, and Norme Francaise (French Institute for Standardization) NF E 11-053 standards, and includes an identification number and a declaration of conformity. The set includes a dial test indicator, a 0.080" (2mm) ball-end carbide contact point, a 0.310"(8mm) extension with dovetail, a point key, a Certificate of Accuracy and Traceability, and a storage box.

Dial readings with three digits, such as 0-10-0, signify that the indicator has a balanced dial. Dial readings with two digits, such as 0-100, indicate that the dial has a continuous dial. Balanced dials are used to read the difference from a specific surface reference point. Continuous dials are used for direct readings and usually have a larger measurement range than balanced dials.

Dial indicators are also called dial gauges, dial calipers, and probe indicators. These precision measuring tools are used to accurately measure small linear distances and object sizes. The dial magnifies the measurement so that it can more easily be read by the human eye. Frequently used in manufacturing, laboratories, and other industrial or mechanical fields, dial indicators are used anywhere a small measurement must be found and recorded or transferred, such as checking the variation in tolerance of a workpiece. Standard dial indicators measure the displacement along the axis of the indicator. Dial test indicators are very similar to dial indicators, except that the axis of measurement is perpendicular to the axis of the indicator. Dial and dial test indicators can be analog, with a mechanical dial, or electronic, with a digital display. Some electronic models transfer the data electronically to a computer for recording and potential manipulation.

Brown & Sharpe manufactures precision measuring equipment and metrology hand tools. The company, founded in 1833, played a key role in setting industrial standards in the United States. Brown & Sharpe was acquired by Hexagon Metrology in 2001 and is headquartered in North Kingstown, RI.
